Title: Load cell with strain gauges
Inventor: WAZAU GEORG DR ING
IPC: G01L1/22
Filed: 1983-12-27
Abstract: In load cells with plate-shaped springs (2), use is usually made of strain gauges (4, 5, 6, 7) with the strands of the rosette parallel to one another and a radial measuring direction. These load cells have a relatively high eccentricity error, a relatively high error due to the heat loss of the supply current and a relatively low sensitivity. By means of a configuration of the strain gauges (8, 9, 10, 11) modified according to the invention, with some of the strands of the rosettes running radially, some running tangentially, a good averaging of the strains is obtained, that is to say no eccentricity error, a good dissipation of the heat loss is obtained due to large surfaces covered by the rosette and high sensitivity is obtained due to optimum utilisation of the strains. <IMAGE>

Title: Device for ventilating a fluid container, in particular a fuel container for motor vehicles
Inventor: SCHEURENBRAND DIETER
IPC: B60K15/035
Filed: 1984-03-30
Abstract: The invention relates to a device for ventilating a fluid container, in particular a fuel container for motor vehicles, having a compensation container which is arranged in the upper part of the fluid container, is connected to the inside of the container and is ventilated to the atmosphere via a compensation line which is connected to a valve device for continuously ventilating the fuel container. In known ventilation devices, the valve device is arranged outside the fluid container. Therefore, it can become inoperative at cold times of the year due to freezing if water vapour has condensed in the compensation container and passes into the compensation line. In addition, vaporised fluid, for example fuel, can enter the compensation line as a condensate and pass out into the open air via the valve device. This is avoided according to the invention in that the valve device is arranged inside the compensation container and has a closed housing which, on the one hand, is connected to the compensation line and, on the other hand, is equipped with a valve arrangement by means of which the interiors of the compensation container and housing can be automatically connected to one another when a partial vacuum or excess pressure arises in the fluid container.

Patent DE-3434565-A1 (DE)
Title: Method for measuring the deformation of sunken pile-driving bodies and drill bodies
Inventor: FREISL PAUL-PETER
IPC: G01M7/00
Filed: 1984-09-20
Abstract: This method can be used in the case of sheet pilings, columns and ground anchors as well as drilling linkages both while they are being fed forward as well as subsequently, and is based on the analysis of the body-sound frequency spectrum of the object to be investigated, which spectrum is governed by the operation or is externally excited.   In this case, the magnitude and distribution of the deformation-typical internal stress are measured indirectly by means of the resonant-frequency shift caused by the latter and are continuously compared with case-specific reference values which are theoretically calculated or are determined in model experiments. The magnitude of the deviation from the required values gives the machine operator continuous information on the quality of drilling progress and thus initiates corrective measures in good time, when necessary. In addition, typical damage responses can be diagnosed from the measurement curves, such as yoke deviations in the case of divergent sheet pilings, and in addition crack formation and the curvature of the longitudinal axis. The latter value can advantageously be used to identify directional deviations of the actual drilling hole axis from that planned, and furthermore, it is possible continuously to check the drilling linkage for excessive material stress.

Title: Method for arranging a conductor layer on the surface of a roadway and arrangement of a heating layer on a roadway surface
Inventor: GEMMER HANS-JUERGEN
IPC: G05D1/02
Filed: 1985-05-02
Abstract: For detecting traffic density, it is known to embed copper wires as induction loops in ducts. The copper wires, which are protected by corresponding coverings, are subsequently covered with a quartz sand layer and for the most part secured with wooden wedges against rising up. The ducts which are cut into the roadway surface are then sealed with hot bitumen. Moreover, it is known to lay copper layers on roadway surfaces and to seal them with plastic. Problems arise in this case, however, in particular in the region of joints as these cannot be bridged without further action. The invention envisages firstly applying a support layer 13 onto the roadway surface 11, then spraying on the conductor layer 15 and finally sealing the conductor layer 15 with a protective covering 14 made of a plastic corresponding to the material of the support layer 13. If the conductor layer 15 is to be applied directly onto the roadway surface 11, there are provided in the region of joints limitedly elastic connection pieces which can be oversprayed without problems. The conductor layer 15 can moreover be used as a heating layer, as a guide track or as a humidity identification layer. <IMAGE>
